2014 Minnesota Fishing Opener Weather
The cool and cloudy weather (and sometimes snowy) has delayed the progress of spring in Minnesota. Lakes in southern and central Minnesota lost their ice from about one week to ten days later than the median ice out dates calculated since 1950. However, ice out for 2014 is running about one to two weeks ahead of 2013, when many large lakes in the north still had ice on them for the fishing opener, including Mille Lacs.
There's been ice on lakes in northern Minnesota in other past years for the fishing opener. The most dramatic besides 2013 was 1950 with lakes still iced as far south as Osakis and Mille Lacs. 1950 was the latest ice out season for the 20th century and many of the late ice out records for lakes with long period of records stem from 1950. Other years with some ice on nothern lakes include: 1966, 1979, 1996, 2008, and 2009.With 2009 there were just a couple lakes in the far northeastern tip of Minnesota still had ice on them.
Minnesota's Fishing Opener weather is typified by partly cloudy to cloudy skies, morning temperatures in the low 40's, and afternoon temperatures climbing to near 70. Three out of four years are free of measurable precipitation. A trace of snow has been reported in northern Minnesota on at least five of the last 64 fishing openers. On at least four occasions, some lakes were still frozen for the opener. Generally there is enough wind to be felt on the face, maybe enough to 'fly' a flag. Weather on Minnesota fishing opener dates is highly variable. 64 years of fishing opener weather data are summarized here to offer a glimpse of what is 'typical' and what is 'extreme'.
Opening day temperatures have started as low as 24 degrees at International Falls (1996,2004), with freezing temperatures possible even in Minneapolis (31 degrees in 1979). On the warm side, St. Cloud saw 92 degrees in 1987, Minneapolis reported 91 in 1987, and International Falls reached 88 in 1977. The average early morning temperature varies from the high 30's in the northeast to the high 40's along the southern border. The average afternoon temperature generally ranges from the mid 60's along the northern border, to the low 70's in the extreme south. Along the shore of Lake Superior, highs are held in the mid 50's.
Three quarters of past opening days have been free of measurable precipitation. Two thirds of the fishing openers have been free of any precipitation, measurable or not. On those days with measurable rain, the amounts averaged close to a half-inch in the south and a quarter inch in the north. No amounts over one inch were recorded at International Falls, while Minneapolis experienced 1.15 in 1962 and 1.64 in 1965. St. Cloud saw 1.03 inches in 2008. Snowfall has generally has been limited to traces. Traces of snow were officially recorded in 1963, 1993, 2009 and 2013 at International Falls, and in 1968 at St. Cloud. A tenth (.1) of an inch fell at International Falls in 2000.
Statewide, less than one year in five offers totally clear skies. The average amount of cloudiness lies near that fuzzy boundary between 'partly cloudy' and 'cloudy', but over half of the dates were classified as cloudy.
Average daily wind speeds generally range between 8 and 15 miles per hour. This range can is described as 'wind felt on face ...' to '... wind extends light flag'. The predominant wind direction is split fairly evenly between blowing from the northwest, south, and east.
Fog has been reported on the fishing opener, occurring about one year in ten in the south, about one year in six in the north. By early to mid May, Minnesota is entering its thunderstorm season. The possibility of thunderstorms is greatest in the south (about one in seven), less in the north (about one in eleven). The weather should be monitored carefully if the skies appear threatening.
For May 10, 2014 at St. Cloud, the sun will rise at 5:56 a.m.; sunset will come at 8:31 p.m. For International Falls, sunrise/sunset is 5:44 a.m. and 8:37 p.m. respectively. For Minneapolis, sunrise will be 5:54 a.m. and sunset at 8:26 p.m. Add one minute for each 10 miles west of a given location (at the same latitude) to get a rough estimate of sunrise and sunset times. Sunrise/sunset information can be obtained for any community using a Web site offered by the US Naval Observatory.
